Just realized that I could probably get a better answer if I explained my situation. I'm shipping a frame with forks via Fedex ground. Is an industry standard bike box the way to go? Or is there something smaller for just frames?

I have shipped a couple of complete mountain bikes in the past month using boxes I got from the local shop. Manufacturers are very smart in sizing the boxes. A typical box will have dimension similar to 51x7x31. This will fall into the category UPS defines as oversize 2. If you change the width of the previous example to 8" instead of 7" you will now be in a oversize 3 category. In my case this changed the shipping cost from $32 to $108. It is very important to make sure you convince the person at the shipping counter that it really measures only 7" and not 8" like they first measured As far as weight is concerned I would guess the box and shipping materials will add 6-8 lbs. As previously mentioned if you are shipping just a frame there are smaller boxes available but they are harder to come by.
